Huge Pages for PostgreSQL, Explained
24 November
Intermediate
HugePages often sound simple ("use large pages for shared memory"), but in practice people get stuck on the same questions: what they actually change, how to calculate the right amount, and how to confirm the system is using them correctly. In this talk I will explain HugePages in plain language, then walk through a clear sizing approach you can repeat on your own systems. You'll leave knowing what to check before enabling them, what common mistakes to avoid, and how to decide if HugePages are worth it for your workload. I'll finish with benchmark results comparing performance with and without HugePages.
